Keeping layer filters active during building

[BasenjiMaster]

Is there a way to keep the layer filters active while I build? It's a huge pain when, say, I want to build a road along the fertile area of a map.

As it is now, whenever you select a road, the filter disapears. So I end up switching back and forth all the time.

Anyone know if there is a mod, or perhaps a way to edit the game as to NOT disable the filter whenever you select something to build?

Yes, if you select fertile areas from the right side of the screen you can use the smallest farm road to outline it. Then you could follow the outline of the small farm road with any other road you choose.
